VAPOR GENERATOR AND snrnnn'narnn.

Application filed September 4, 1924. Serial No. 735,862.

My invention has relation to improveof the housing 2, the drive shaft 1 of which ments in vapor generatorsand superheaters projects through the top wall of said housing and consists in the novel features of conand carries on its extremity a fan or exstruction more fully set forth in the specihauster 3, the intake opening of which 60 [ication and pointed out in the claims. receives the upper end of the flue 5. The

The principal object of the invention is to side walls of the housing 2 are each progenerate steam and cause the same to be vided with an outlet opening 16, two of superheated by increasing the pressure therewhich communicate with hollow ironing of within a suitable mixing chamber wherein tables 8 and 9 and one of which (in the 10 the steam is mixed with hot gases. Applipresent instance) has connected to it a flexcant is aware that heretofore steam generaible hose 11 terminating in a brush 12. tors have been devised wherein the steam It is understood that from the opening was mixed with hot gases, but the degree to 16 the steam may be led to any desired which the steam could be heated was limited point of application for such purpose as T5 in these-devices owing to the fact that no one may see fit, such as heating or even provision was made for increasing the prescooking. sure thereof above that of atmospheric pres- The operation of my invention briefly may sure. Applicants improvement contembe described as follows:

plates the provision of a fan or other device We will assume that the water container mixed with a large volume of hot gases in water and that the gas is turned into the a confined chamber where their pressure. is burner 6 and ignited. Thereafter, the steam greatly increased. and vapor will rise within the container 4:

The manner of accomplishing this object and the products of combustion and hot gases 25 together with the other advantages poswill rise within the flue 5, said steam and sessedby this invention will be better ap. heated products of combustion commingling parent by a more detailed description of the within the upper part of the flue 5 and then same in connection with the accompanying discharging into the casing G which serves drawings, in which as a mixing chamber. Now, if the fan 3 3 Figure 1 is a vertical longitudinal section is not in operation the steam will move taken on the line 1-1 of Fig. 2 (with parts slowly under the influence of atmospheric in elevation) of my improved generator and pressure into the hollow tables 8 and 9. But superheater; Fig. 2 is a plan view of the inon putting the fan 3 into operation the steam vention; and Fig. 3 is a horizontal cross and products of combustion will be rapidly section on the line 3-.3 of Fig. 1. exhausted by the action of the fan from the Referring to the drawings, B represents'flue 5 and expelled into chamber C at the a suitable base extending upwardly from same time being rapidly and thoroughly which is a hollow pedestal 7 on the upper mixed within said chamber. Since the outend of which is fixed a housing 2 provided let of the mixed steam and products of comwith a downwardly extending annular flange bustion from the chamber C is inadequate 2 which receives the edestal 7. Positioned to allow such products to discharge freely within the pedestal i at about the middle from such chamber the pressure of the steam thereof is a gas burner 6 above which there within the chamber will be greatly increased is a water container or a boiler 4. Within and the steam will therein become super- 109 the boilerand disposed along the axisthereheated and discharged with greatly inof is a flue or open ended pipe 5, said flue creased velocity through the opening 16 in being provided with a series of annularly the housing wall 15. The great advantage disposed openings 10 immediately below the of superheated steam at high pressure withhottom wall of the housing 2. The space bein the casing C is that the steam may be 50 tween the boiler 4c and the top of the pedestal conducted by means of a pipe connected to 7 is closed by a wall to so that the only either ofthe outlets, 13 or 14C to some reason outlet for the steam and vapor arising withably distant point which could not be done in the boiler at is through the openings 10 if the steam exhausted in the casing only I into the flue 5 whence such products dis under atmospheric pressure. 1m 55 charge into a mixing chamber C within the pHaving described my invention, I claim:

housing 2. A motor 1 is mounted on the top 1. A. steam generator and superheater comprising a burner, a Water container adacent thereto, a flue for the products of combustion from the burner ad acent to the Water container, a housing having a m1x ing chamber in communication with both the Water container and the flue, and a fan for exhausting the products of combustion from the flue into said mixing chamber, said chamber having restricted outlets.

A steam generator and superheater comprising a burner, a Water container adjacent thereto, a flue for the products of combustion from the burner Within the Water container, a housing having a mining chamber, a fan Within said mixing chamber, said tan having an intake in communication With the water container and flue and an outlet comniunicating with the mixing chamber, and said mixing chamber having restricted outlets.

A steam generator and superheater comprising a Water container, means for heating the Water therein, means associated with said Water container for superheating the steam generated therein, a housing having a chamber in communication with the Water container, said chamber being pro vided With restricted outlets, and means for increasing the pressure of the vapor in said chamber above atmospheric pressure.

A steam generator and superheater comprising a Water container, means for heating the Water therein, means associated with said Water container for superheating the steam generated therein, a housing having a chamber in communication with the Water container, said chamber having a restricted outlet, means for increasing the pressure of the taper in said chamber above atmospheric. pressure, and means associated with said superheating means for introducing heated atmospheric air in the said chamber.
